I am working on Football Club Academy project based on LEED NC 2009 and AGMBC 2011.
My understanding is that the lighting power density for the external floodlighting is required to comply with a figure of 2.15 W/m2 as it’s been classified as ‘a special feature area’ under ANSI/ASHRAE/IESNA standard 90. 1-2007.
Campus project has 6 Football pitches and the designed floodlighting power densities are in excess of 2.15 W/m2 and are driven by the project specific requirements for the pitches.
Following is the extract from NC 2009 for SCHOOL - SS Credit 8: Light Pollution Reduction
Sports Field Lighting (Physical Education Spaces)
Physical education spaces (playing fields) do not need to comply with the lighting power density requirements of this credit, as per ANSI/ASHRAE/IESNA Standard 90.1-2007 section 9.4.5, exception E.
Automatic Shutoff: All sports lighting must be automatically controlled to shut off no later than 11 p.m. Manual override must be provided to avoid disruption of school sponsored sporting events
1.Could the exclusion of the sports field lighting clause be applicable to Football club academy registered under LEED 2009 NC as well?
2.Could I exclude the sports field lighting (floodlights power density) from energy simulation for EAp2 Minimum Energy performance as well?
Thank you in advance

You cannot exempt the sport field lighting for EAp2.
It is exempted from the requirements of 90.1 and is therefore not a "special feature area". As such there is no defined baseline value and it is treated in EAp2 just like any other non-regulated lighting. Model the design of this lighting the same in the proposed and the baseline and indicate it is process lighting. It is a good idea to explain this to the reviewer to avoid any potential confusion.

Also, be careful trying to proove baseline lighting performance and a comparable improved design case performance for sport field lighting (which like a process load is usually the same in both models). In my experience, the lighting performance requirements are standards set by the needs for HD television recording, and although I have come across "more efficient" lighting, it had the down-side of shorter life spans for the illuminators (also meaning more maintenance). This was back in 2009...so there may obviously have been improvements.

Hi, my project on new factory has football pitch facility on the 2nd floor. Since it is on the higher level, it does not causes any light pollution reduction. I am assuming the lighting specification for the football pitch does not has to meet BUG rating. Also, any activities will only allowed until 10pm where the lights will be shuts off.
Please verify if this would still complying with Light Pollution Reduction credit

I would suggest you post your question in the forum for the Light Polution credit.
